    • Interleaved black/bright imaging (IBBI) is performed using a magnetic resonance (MR) scanner (10) wherein the black blood module (52) of the IBBI includes: applying a first flow sensitization gradient; applying a spoiler gradient after applying the first flow sensitization gradient; applying a second flow sensitization gradient after applying the spoiler gradient wherein the second flow sensitization gradient has area equal to the first flow sensitation gradient but of opposite polarity; applying a slice selective radio frequency excitation pulse after applying the spoiler gradient; and performing a MR readout after applying the second flow sensitization gradient and after applying the slice selective radio frequency excitation wherein the readout acquires MR imaging data having blood signal suppression in the region excited by the slice selective radio frequency excitation pulse. The MR imaging data having blood signal suppression is reconstructed to generate black blood images (20), and MR imaging data generated by bright blood modules (50) of the IBBI is reconstructed to generate bright blood images (22).
    • 使用磁共振(MR)扫描器(10)进行交错黑/亮成像(IBBI),其中IBBI的黑血模块(52)包括:施加第一流感敏化梯度; 在应用第一流感敏化梯度后应用扰流板梯度; 在施加扰流板梯度之后施加第二流动增感梯度,其中第二流动增感梯度具有等于第一流动感觉梯度但具有相反极性的面积; 应用扰流板梯度后应用切片选择性射频激励脉冲; 以及在应用所述第二流敏增强梯度之后并且在施加所述切片选择性射频激发之后执行MR读出,其中所述读出器获取在由所述切片选择性射频激励脉冲激发的区域中具有血液信号抑制的MR成像数据。 重建具有血液信号抑制的MR成像数据以产生黑血图像(20),并重建由IBBI的亮血模块(50)产生的MR成像数据,以产生亮血图像(22)。

    • A magnetic resonance system (10),and corresponding method, image a subject using a conversion-free interleaved black and bright blood imaging (cfIBBI) sequence. A MR scanner (12) is controlled to perform a plurality of repetitions of a black blood imaging sequence (52). The black blood imaging sequence (52) includes a tissue nulling sub-sequence followed by a black blood acquisition sub-sequence (56) performed a time interval (TI) after the tissue nulling sub-sequence. The MR scanner (12) is further controlled to, between successive repetitions of the black blood imaging sequence (52), perform a bright blood imaging sequence (54) including the tissue nulling sub-sequence followed by a bright blood acquisition sub-sequence (58) performed the time interval (TI) after the tissue nulling sub-sequence. The time intervals (TI) of the black blood imaging sequence (52) and the bright blood imaging sequence (54) are of the same duration.
